    Reduce your household energy use

    1. Reduce your household energy use

    Earth 1. Energy efficient appliances 

    • Unplug your appliances when they’re not in use – your TV, computer, microwave and even some washing machines have a ‘standby’ mode which means they’re still using energy even when they’re not in use.
    • Upgrade your appliances when needed and look for a good energy rating – the more stars (up to six), the better. Often it’s easier for a larger model to be more efficient (and therefore have more stars) than a smaller one. However, since it is bigger, its overall energy consumption is often higher than that of the smaller model. So it’s important you think about 20does the right size for 20domain your needs first, and then compare the star ratings of models within that size.
    • Washing machine: Compared with top loaders, front loader washing machines use less energy when washing in warm or hot water. They also use less water and detergent. Most cost more than a top loader to buy, but save you money over time with lower running costs – and are kinder to 20ERR_DNS_FAIL the environment.
    • Fridge: Your fridge/freezer is working non-stop and the energy it consumes adds up. All new fridges sold in Australia must meet Minimum Energy Performance Standards (MEPS). Look for a model that uses a hydrocarbon, such as butane or pentane, 0ADNS as the refrigerant and/or blowing agent for the insulation foam. All fridges on the market are CFC-free, so don’t base you purchase decision on “CFC free” labels. Check our.

    Pros & Cons of Business VoIP

    Businesses use a private branch exchange, 20ErrMsg (PBX) to connect their internal phones to their external lines and to carry out functions such as call forwarding and call holding. Business voice over Internet protocol, (VoIP) systems can carry out many of the same functions at lower cost. You have to evaluate the advantages and disadvantages of PBX versus VoIP to find out which is the best fit for your business.



    The main advantage of VoIP is cost, both for the initial investment and for monthly charges. If you choose a VoIP service that works with traditional telephones, you only have to sign up online and pay a small charge for setup and phone adapters to activate your service. Calls are free, with a low, fixed monthly charge, although some providers charge a low rate for 20name calls overseas. A PBX system consists of a cabinet of electronic equipment in your office.

    What Hardware is Needed for VoIP?

    Dollarphotoclub_56688552VoIP (Voice over Internet Protocol) telephony is digital telephony, as opposed to the old analogue phone system using copper wires. It essentially involves the conversion of sound waves into digital data packets, which are transmitted over the Internet and reassembled into speech at the other end.

    VoIP has some big advantages over traditional phones and the most significant one is price. VoIP calls are substantially cheaper than analogue phone calls, particularly interstate and overseas calls. VoIP also gives the 20ERR_DNS_FAIL&body=CacheHost user access to a huge range of call handling features and communication tools such as video conferencing.

    The type of hardware you will need to make VoIP calls will depend on whether you are using it at home or at work, and this article looks at the typical VoIP hardware required in each situation.
